<p>A lifting device (1) for goods containers (35) includes a body member (2). Four inner pickup elements (7, 8, 9, 10) are movably mounted on the body member (2). Two first extendable members (3, 4) are movably mounted on the body member (2) for movement between a first position in which the first extendable members (3, 4) are not extended from the body member (2) and a second position in which the first extendable members (3, 4) extend from opposite ends of the body member (2). Two second extendable members (5, 6) are provided with one second extendable member (5, 6) being mounted on each of the first extendable members (3, 4). Each second extendable member (5, 6) is movably mounted on the respective first extendable member (3, 4) for movement between a first position in which the second extendable member (5, 6) is not extended from the first extendable member (3, 4) and a second position in which the second extendable member (5, 6) is extended from the first extendable member (3, 4). Each second extendable member (5, 6) has two outer pickup elements (17, 18, 19, 20) mounted adjacent the end furthest from the body member (2) when the second extendable member (5, 6) is in the second position. In addition, two of the inner pickup elements (7, 9) are fixedly coupled to one of the first extendable members (3) for movement therewith and the other two inner pickup elements (8, 10) are fixedly coupled to the other of the first extendable members (4).</p> |
